Abstract
1371132 Centrifugal submersible pumps GARVENSWERKE PUMPEN-MOTOREN-UND OLDBRENNERFABRIK W GARVENS 22 Feb 1972 [25 Feb 1971] 8146/72 Heading F1C In a submersible deep well set comprising two or more pumps 1, 2 arranged one above the other in a lining pipe 6, the lower pump 1 discharges through a tube 3 into the lining pipe 6 above a cup seal or an O-ring seal 4 which prevents backflow of liquid to pump 1. Thus the lining pipe 6 above seal 4 constitutes an intermediate container for booster pump 2 which discharges through pipe 5. The O-ring seal (11) may be forced against the lining pipe by the liquid discharged by pump 1 flowing through bores (12) Figs. 2 and 3 (not shown). Power may be supplied to lower pump motor by wires which extend through stator slots of the upper motor.
